It's because x^a / x^a = 1
LHS = x^(a-a) = x^0 = RHS = 1

x^a/x^b = x^(a - b)
so x^a/x^a = 1 = x^(a -a) = x^0

x^4 / x = x^(4 - 1) = x³
x³ / x = x ^(3 - 1) = x²
x² / x = x^(2 - 1) = x^1
x / x = x^(1 - 1) = x^0
But x / x = 1
Thus x^0 = 1

I assume you`re familiar with the 2nd rule of indices,
p^c divided by p^d = p^c-d.
Consider p^7 divided by p^7, then by the second rule, this is
equal to p^0.
However, we know that any number divided by itself, say
17 divided by 17 = 1,so,. p^7 divided by p^7 = p^0 = 1
Hence any number raised to the power of zero is one.

x^6/x^6 = 1
and
x^6/x^6 = x^0
=> x^0 =1

given the formula:
(x^a) / (x^b) = x^(a-b)
and
C/C = 1 for any non-zero C.
Let C = x^a
then
C/C = (x^a) / (x^a)
1 = x^(a-a)
1 = x^0

If x not equal to zero, choose any m not equal to zero.
x^0 = x^(m-m) = (x^m)(x^-m) = (x^m)/(x^m) = 1
